Title: Method and apparatus for detecting hydrogenated gas
Inventor: INOUE MASAO
IPC: G01N5/02
Filed: 1990-10-01
Abstract: PURPOSE:To easily detect fine particles due to hydrogenated gas such as silica by mixing ozone generated from an ozone generating means into air containing hydrogenated gas to generate a nucleus of a fine particle (critical nucleus) from the hydrogenated gas. CONSTITUTION:Air in an atmosphere containing silane gas for example as hydrogenated gas is led into a measurement chamber 1, whereby silane gas is oxidized by ozone generated by an ozonizer 3 to generate a critical nucleus of silica. The critical nucleus generated by oxidization of ozone is physically adsorptive and is attached to a surface of a crystal vibrator 4. On the other hand, a detecting circuit 6 monitors the number of vibrations of the crystal vibrator 4 constantly or with constant time intervals. When the critical nucleus of silica attaches to the surface of the crystal vibrator 4, a mass of the crystal vibrator 4 increases to have the number of vibrations changed. The change in the number of vibrations of the crystal vibrator 4 corresponds to the attached silica critical nucleus, that is gas concentration of silane in the atmosphere. When the number of vibrations reaches a predetermined value, a warning signal is sent to alarming equipment, etc. so that necessary alarming operation such as a lamp and buzzer is performed.

IPC: G03G9/113
Filed: 1984-12-12
Abstract: PURPOSE:To enhance fluidity, conveyability, and durability by grinding the surfaces of apparently spherical powdery particles composed of aggregates of minute particles composed mainly of fine iron particles, and coating the ground surfaces with an insulating material. CONSTITUTION:The spherical carrier material is composed mainly of the aggregates of fine iron particles, there are a large number of pores in the inside of each spherical carrier particle, and it looks like the smooth surface of each sphere coated with a large number of fine particles, and innumerable ruggedness are observed.

Abstract: PURPOSE:To sail along a scheduled waterway and to lay a net corresponding to the length of a wound net by displaying the best course of expected net laying as the scheduled waterway in advance. CONSTITUTION:A CPU 6 reads its ship position S out of a position measuring instrument 2 prior to the start of net laying to calculate its display position on the screen of a CRT 12, and also reads the flow direction and flow velocity of a tidal current T out of a tidal current meter 1. Then the scheduled waterway C is calculated when the net begins to be laid. For the purpose, the winding shape C' of the net after the net is laid is calculated from length data on the wound net and the time required for the net laying is calculated from the wound net length and the relative water speed of the ship. Then the drifting distance of the net is calculated and vector-subtracted from the initially set winding shape of the net to calculate and display the scheduled waterway C after the influence of the tidal current is corrected on the CRT 12. Then the ship is sailed along the scheduled waterway C to lay the net, and then the wound net is laid circularly as shown by the winding shape C' at the end of the net laying.
